An 11-year-old autistic boy is cooking up an internet storm with his unbelievable ability to draw a map of the world freehand, from memory!

The boy’s mom is a college professor, and he happened to sit in on one of her classes a few weeks ago. During the class, he apparently walked up to the whiteboard and reproduced the entire map of the world, complete with the names of the countries. The students in the classroom were so amazed that they immediately took pictures with their phones, which eventually got posted on news sharing site Reddit.

Stephen Wiltshire, who is autistic,drew in detail a 7 square-mile area of London from his own memory after just a 20 minutes flight with the helicopter over the city.The artist has amazed everyone by drawing hundreds of London’s buildings in exact scale, such as the Swiss Re tower or Canary Wharf on a 13ft curving canvas in 5 days.

Stephen,actually named as “the human camera”,was diagnosed with autism at the age of three.At that early age he was unable to make himself understood.Some teachers from Queensmill, a school in Fulham for special needs children,forced him to shout “Paper!!!” by taking away his materials and then he managed to develop language skills by learning words related to his work.Now,at the age of 33,Stephen Wiltshire is capable to communicate with others,leading an independent life.
